Correct weather-resistant steel plate processing and doing old ways

Correct weathering steel plate processing and old ways:

1, material selection: not all the weather-resistant steel plate is the weather-resistant steel plate you want. There are many businesses to acid resistant plate, salt resistant plate, ship plate are called weather-resistant steel plate to sell, but the rust produced by these steel plates will not be the effect you want. But this steel plate can also be barely called weather-resistant steel plate, worse than this, there are businesses to sell ordinary steel plate as a weather-resistant steel plate, from the appearance of ordinary steel plate and weather-resistant steel plate there is no difference, and in a short period of time if you do not go to the test, then you can not find, just a year or two later, the raw rust is like a pancake off the shell.

Generally, there is a plate label and the manufacturer's material book on the plate label. On the plate label, we can see the words Q355NHB in the second row, where Q355 indicates its yield strength, and NHB indicates that it is a weathering board; The third row indicates the thickness, width and length of the steel plate. Of course, just look at these two are not enough, now the change of the board in the market has been common, the important thing is to find a reliable supplier, more reliable than this is to issue a detailed invoice according to the specifications of the board you buy, the material, because the current traders have to do input and output consistent, generally speaking, it will be better.

2, processing molding: cutting is, of course, laser cutting, its accuracy is currently high cutting tools, of course, thick weathering steel can also choose CNC plasma, CNC flame cutting, this will have to directly manufacturers to see its strength, the same laser cutting its cutting thickness, width, length are not the same, even if some equipment can barely process will affect its precision. And the weather-resistant steel plate molding is more particular, in addition to good bending, bending equipment, the important thing is the technical workers. Like the birds we did, there's a lot of detail.
